Outline of Final Research Achievements

In this study, we investigated the conditions for controlling metal nanoparticles that melt at room temperature, and used these metal nanoparticles to investigate multifaceted ways of incorporating metals into polymer and fiber materials. By identifying the conditions through trial and error, we were able to convert the metal nanoparticles from a stable state to an unstable state, and were able to impart electrical conductivity and catalytic activity to a wide range of materials. In particular, the catalytic activity varied greatly depending on the structure of the final metal produced. Structures with high catalytic activity were developed depending on the adjustment of the conditions.

Academic Significance and Societal Importance of the Research Achievements

高分子・繊維材料と金属材料は、私たちの身の回りにあふれ、現代の豊かな社会を支えている基本的な材料であり、それぞれ、独自の有益な性質を持つ。しかし、これらの材料の加工法は、全く異なっており、高分子・繊維材料と金属材料を融合させることは容易ではない。本研究では、金属ナノ粒子を用いて、幅広い高分子・繊維材料を導体や触媒に変える方法を提案しており、室温近傍で簡単に材料加工が可能なことは、大きな利点と考えられる。
